I've been taking 10,000 IU (with K2) for couple decades now.
The only thing wrong with my health is that I have type 2 diabetes. I'm taking Metformin and Mounjaro for that.
Same here. 10.000 IU with k2 for a few years. I’m 70. Other than the knees and back, I seem to be doing ok for an old overweight woman. Just retired last year after writing a grant for my job. My mind seems to be working ok.
Now if I could just remember my name.....(jk!)
Magnesium as well?
Magnesium activates D3 and the activated D3 works with K2 to Keep Calcium out of your arteries and deposit in bone.
Stronger, more dense bone and less atherosclerotic accumulation in arteries.
(Works for me.)
